He ran 6.7h like 4-5 days before he ran a 10.0. Mo ran slower HT (still 6.7h) and sub 10 (9.9).
Realize basically none of these camps are doing any electronic timing in training, hence why I have to laugh at this “photocell” stuff. These guys are doing HT from first movement, first foot contact, or second foot contact depending on which group you go to. Round up to the next tenth and add .25 at best for most of these times, round up and add .5-8 for some others.
Seagrave said something like he’s never had anybody run within 3% of their PR in practice, most people being 4-8% off their PB levels (competition PB that is) in training.
